"It's fun to win," Williams said. "It's fun to be up and not down 20."
DeShawn Stevenson added 15 points for the Nets, who made a season-high 15 3-pointers to win for the first time since their opener, Dec. 26 at Washington.
"We needed a win in the worst way," Williams said. "I think everybody realized that tonight and we buckled down defensively."
Nets coach Avery Johnson was happy to see his players enjoying the victory in the locker room.
"We wanted to smile," Johnson said. "For five or so games we've been having a frown on our face and we wanted to smile after a game."
"We really were in desperate need of a win tonight," Humphries said.
Fifteen of New Jersey's 31 field goals were from beyond the arc. The Nets made four 3s in the first quarter, five in the second, two in the third and pulled away with four more in the fourth, leading by as many as 21 points.
Stevenson said Williams was the key factor in creating opportunities for New Jersey's outside threats.
"When you have two shooters like me and (Morrow), they've got to pick which one. I got open 3s, (Morrow) got open 3s. That's the way you've got to play.
"That's why I came here," Stevenson added. "(Williams) is an All-Star point guard, he does great things out there. If you put him in a situation where the court is spread, we can get wide-open jumpers all day."
"It goes back to us not stepping on the court and playing desperate," coach Dwane Casey said. "Not playing tight, but playing like a desperate, hungry team and I don't think we did that tonight."
Toronto's DeMar DeRozan, who made a career-high five 3-pointers in Wednesday's victory over Cleveland, was held to three points in this one, hitting just one of six field goal attempts and spending most of the fourth quarter on the bench.
Johnson credited Stevenson's tough defense as the key to keeping DeRozan in check.
"The player of the game for us was DeShawn Stevenson," Johnson said. "The defense that he played on DeRozan was incredible."
Already without center Brook Lopez (broken right foot), rookie guard MarShon Brooks (sprained left ankle) and forward Damion James (sore right foot), the Nets lost starting center Mehmet Okur to back spasms 3 minutes into the opening quarter.
But they were boosted by Williams, who returned after missing Wednesday's loss at Boston with sore ribs, and Humphries, back after skipping the previous two games because of a sore left shoulder. Both were in the starting lineup.
Morrow scored 14 points in the first half to give New Jersey a 48-40 lead at the break, Toronto's largest halftime deficit of the season.
